nay hardware hackers on this forum? If not then u wont get much help here. I know i can not oc my laptop due to the option not being there. There are no options in bios for ocing. which i understand why prebuilts are like that.

Most video cards in any computer can be OCed, in my Inspiron 6000 with an X300 it can be overclocked, im pretty sure it would overheat though. Yeh be careful of those batteries have a look on the dell site and make sure your battery isnt in the list.
